Performance analysis of integrated cellular and ad hoc networks system in the dead spots

首先介绍了一种在盲区环境下集成移动蜂窝和ad hoc网络的系统结构,接着分析了在这种环境下集成系统可获得中继节点的概率。然后结合这个概率,建立了集成移动蜂窝和ad hoc网络系统的解析模型,并且在这个模型的基础上,通过数学解析方法分别得到了传统蜂窝和集成网络系统的会话丢弃概率。最后通过数值仿真比较了在盲区环境中2种系统的性能,并分析了各种系统参数对集成移动蜂窝和ad hoc网络系统性能产生的影响。

A new architecture of integrated cellular and ad hoc networks system in the dead spots was introduced, and the system＇s relay-availability probability under this environment was analyzed. Then by combining with the relay-availability probability, build the analytical model of integrated cellular and ad hoc networks system, and based on this model, get the call dropping probability of the traditional cellular system and integrated cellular and ad hoc networks system respectively by mathematical analyzing. Finally, through numerical simulation, compare the two kinds of system＇s performance under the environment of dead spots, and analyze the impact of the various parameters on the integrated cellular and ad hoc networks system＇s performance.
